As a Bounty hunter I once made a mistake by selling tokens from Bounty that I received in a small market for $ 250. After 20 days the price of tokens that I sell is worth $ 1200. So the conclusion if you want to wait you will get maximum results. Believe every ICO project will prepare a good market in the future.
We have all been there, but it can easily go another way and you regret not selling early while there is still hype of coming to new exchange. You should really focus on the development of their product.
